certain new and useful Improvements in Gas-Cocks, of which the following is a specification. I

This invention relates to improvements, in

gas cocks. The primary object of the invention is to provide a cock which, while especially adapted for use in connection with street lamps, nevertheless, is well adapted for house or indoor use.

In the use of a device of this character un'- der present li hting conditions, it is desirable to embo y in the cock, various characteristics, whereby it may be adapted for use in connection with a pilot-burner, and to provide means whereby when anv inverted mantle is used to insure invariable lighting of the light at such mantle, ratherthan at the bunsen which is an undesirable result that frequently occurs unless provisions are made against it. I

A further object is the provision of means for controlling thegas supply to feed the pilot either continuously, as where the pilot burns for twenty-four hours, or both when the main supply of gas is on and the light lighted, or at such times only when the gas is extinguished, or the main supply of gas cut off. a I

A further object of the invention is to combine in a single structure, means for operating either a twenty-four hour pilot, or a pilot which is only lighted when the main supply of gas is turned on, and a means for insuring the proper lighting of the lamp when an inverted mantle is employed, and

. the invention further contemplates provision of means for tensioning the valve operating the lever, so that it will remain positively in either of its extreme positions, thus obviating the objections incident to the lever being jarred from a set position by vibrations incident to the lamps.

In the drawings- Figure 1 is an edge elevation of the burner;

Fig. 2 is a. transverse central section thereof,

Fig. 3 illustrates series of positions of the valve, and:

F 1g- 4 is a modified form ofthe cook 5 wherein an inverted mantle is employed.

The numeral 1 designates the body proper, which is preferably cast with a lateral extension 2 having a pilot-channel 3 terminating short of the, This channel is internally threaded at its upper end for the reception of the pilot tube 4. Within the extension 2, and at right angles to the pilot-channel are two smaller ducts 5 and 6 both. of which communicate with the pilot-channel while the channel 5 communicates with the valvefbo-re 7, of the cools, and the duct 6 communicates with the main supply channel below the valve or.

will be more particularly described farther along. I I The numeral 14:, designates another lateralextension of the cock which is provided with a flush channel 15, communicating with a small duct 16, whose inner end communi- 5 cates with the valve-bore 7 V The flow of gas from the VfLIVBT'bOI'B to.

the channel 15 is controlled by a needle valve 17 threaded into the extension 14in the samemanner as the valves 12: and 13.

The upper end of the flush'channel 15, (see form shown in Fig. 4,) is threadedfor the reception of a flush tube. V I The valve 9 is provided with a main channel 22, which is adapted tobe brought into" and out of registry with the lower reduced portion 23 of the main channel 21 in the upper part of the body, to establish or cut ofl, as the exigencies of the case may require, the

flow from the gas supply tothe mantle or too other point of consumption. Intersecting the channel 22, and at an angle thereto I provide in the valve anauxiliary duct'24, V which is adapted at times, to register w1th bottom. of the extension. 60

gas supply. The

the duct 16 so as to establish communication between the gas supply and the flush tube, when the burner is of the type shown in Fig. 4.

Since the cock illustrated is intended for connection with a clock or time mechanism.

I provide the body with offsets 25, and 26 to which are attached from the valve seat, as will be apparent. It v has been foundin practice that no matter how accurately the valve may be fitted in its bore or seat, it will in time, without some provision to prevent it, become loosened and fail to stay in any one of its adjusted positions, due generally, to vibrations the burner is subjected to. To overcome this, I provide the operating lever with an extension 31, of

resilient material, which extension is provided at its end with a bearing portion 32' which engages the side of the extension 14:, in all positions of the operating lever. This resilient frictional contact with the body serves to keep the lever and valve to which it is connected always in the position to which it has been moved, thus assuring accurate registry at all times between the duct and channel of the valve, and ducts and channels in the body proper.

Referring to the form shown in Fig. 4, the numeral 33" designates a burner tube connected 31124 to the gas cock section. This tube iscurved at its upper end as shown, and providedwitlrthe mantle-holder 35 of the inverted type. Interposed between the gas cock proper and the mantle is the usual bunsen 36. The numeral 37 designates a flush tube whose lower end communicates with the flush channel 15, the upper end of the tube being let into the tube 33 at a point intermediate between the mantle and the bunsen, so that when the burner is used with this type of mantle the operation of the operating lever will let into the tube above the bunsen, a puff of gas, suflicient to fill the chamber or space in said tube intcr vening between the mantle and the bunsen, so that the danger of-a flash-back and consequent lighting at the bunsen is entirely overcome.

Referring particularly to Fig. 1, it-will be notedthat the parts are so positioned that plates or brackets 27- and 28 having therein open slots 29 which there is direct communication between the source of gas supply and the body proper, the duct 5 being closed by the valve. When the operating lever 30 is raised the solid part of the valve will cut off comnumicatiou with the channel 23, andestablish communication with the pilot, as shown in subfigure Z); Assuming now that it is desired to use the pilot, at all times, both when the main flow is 01?, and when it is on; it is only necessary to so adjust the needle valve 13 that communication will always be estab lished between the duct 6 and main channel 8. At such time the duct 5 may be open or closed, as maybe desired. Now assuming that the cock is used in connection with the inverted type of the burner as illustrated in Fig. l, and in such a case assuming the parts to be as shown in Fig. 1, when the operating lever is be brought momentarily in registry with the duct 16 permitting a quantity of gas to pass raised, the duct 2l will into the flush channel 15, through it to the flush tube 37. This occurs in the downward opening movement of the operating lever and when the parts are in the position shown in sub figure c, and just prior to the straightening up of-the duct 22, in the valve 9.

Having thus described my invention what I claim is 1-. A gas cock comprising a body havinga main passage therethrough, and a valve-bore intersecting said passage, a valve in said passage formed with a cut-away portion, and a channel adapted toregister with the main passage in the body, andalso with an auxiliary duct communicatingwith a channel in the valve, said body being formed with an extension having therein a flush channel and duct communicating with the valve-bore and with the flush channel, the duct'in the valve beingadapted to momentarily register with the last mentioned duct in shifting from one extreme position to the other, whereby a-pufi of gas is permitted to pass through the flush channel, and means for regulating the flow of gas to said flush channel;
